The R120G knock-in mutation in αB-crystallin is insufficient to induce cardiomyopathy in mice.

Abstract excerpt

Alpha B-crystallin (CryAB) is a small heat-shock protein highly expressed in cardiac tissue, where it functions as a molecular chaperone that helps prevent protein aggregation, particularly under stress conditions. A missense mutation in CryAB (R120G) causes autosomal dominant cardiomyopathy in humans and is characterized by extensive protein aggregation in cardiomyocytes. To better understand the pathogenic...
